ARTHUR MOGONAGLE, OF EAST ORANGE, NEW JERSEY, ASSIGNOR TO STARRETTCOTTON GIN COMPANY, OF NEW YORK, N. Y., A COR- PORATION OF NEW YORK.

COTTON-GIN.

SPECIFICATION forming part of Letters Patent No. 759,390, dated May 10,1904.

Application filed June 26, 1903.

To all whom, it may concern.-

Be it known that I, ARTHUR MoGoNAeLE, a citizen of the United States ofAmerica, anda resident of East Orange, county of Essex, State of NewJersey, have invented certain new and useful Improvements inCotton-Gins, of which the following is a specification, referenceb'einghad to the accompanying drawings, form ing a part thereof.

My invention relates to improvements in; cotton-gi ns, andparticularl yto the form of gin, known as the roller cotton-gin.

My. invention consists in the employment of air-currents in combinationwith a roller and tral vertical transverse section of a cotton-giniembodying my invention, the section being;

taken upon the plane of the line 1 1 of Fig. 2.- Fig. 2 is a top view ofsame with portions.

thereof broken away. For the sake of clearness and intelligibility. Ihave illustrated herein acotton-gin in its simplest form, partsunnecessary for a complete understanding of my invention beingeitheromitted or shown conventionally, so as not to obscure the more essentialfeatures thereof. 7 p

A roller (4 is provided, suitably mounted in. bearings supported by aframe I) and has a plu rality of spirally-disposed projections or ribsc. These projections or ribs may conveniently be formed of walrus hideor other leather and" Serial No. 163,167. (No model.)

roller a stripper g separates the casing from the hopper and coacts withthe periphery of the roller for the purpose of ginning the cotton,.whileat the rear of the said roller the casing converges toward a point h inclose proximity to the periphery of the roller, for a purpose presentlyto be described.

A seed-board a of any suitable construction may conveniently form onewall of the seedhopper and terminates in proximity to the stripper. v

In carrying out my invention I provide means for creating a draft and socausing air-currentsto pass between the face of the stripper and theperipheryof the roller into and through the casing and for this purposehave shown herein a fan-blower or suction apparatus connected on itsinlet side with the lower end of the said casing. .At its dischargesidethe said fan-blower may connect with any desired point of delivery,such as the balingpresses commonly employed in baling cotton.

In operation cotton is supplied to the hopper f and rests against theseed-board, the

stripper, and theperiphery of the ginningroller. The ginning-roller is.then revolved in the direction of the arrow, Fig. 1, and thefan-bloweris simultaneously operated to create a suction within thecasing The combined action of the air-currents with the discharged inany suitable manner. No mechanism is herein shown for operating theseedboard, as the same forms no part of my present invention.Air-currents will not only be drawn into the casing between the stripperand the ginning-roller, but will also be drawn into the casing betweenthe contracted portion it thereof and the periphery of theginning-roller upon the side opposite to that at which the stripper isdisposed. The efiect of the currents of air passing the point it will beto strip from the roller the fibers of cotton, which are received in thespiral grooves (Z and have a tendency to be carried completely round bythe roller in its revolution. The point it being in quite closeproximity to the periphery of the roller the currents of air will bedrawn into the casing through the grooves d, and this will tend to verythoroughly clean and strip the roller of fibers. The cotton fibersreceived into the casing will be carried down into the suction apparatusand delivered thereby at the discharge side thereof to any desiredpoint.

What I claim is 1. In a cotton-gin, the combination with a roller and astripper adapted to cooperate with the periphery thereof in a ginningoperation, of means for causing the air-pressure on one side of thepoint of coaction of the said stripper with the said roller to be lessthan that on the other side.

2. In a cotton-gin, the combination with a roller and a stripper adaptedto cooperate with the periphery thereof in a ginning operation, of meansfor disturbing the equilibrium of air-pressure at the point of coactionof the said stripper with the said roller.

3. In a cotton-gin, the combination with a roller and a strippercoacting therewith, of

means for causing air-currents to pass between the periphery of theroller and the stripper.

1. In a cotton-gin, the combination with a roller and a strippercooperating therewith, of means for drawing air between the periphery ofthe roller and the stripper.

5. In a cotton-gin, the combination with a roller and a casing partiallyinclosing same, of a stripper forming a closure for the casing at oneside of the said roller, and arranged with its edge in close proximityto the said roller, and means for causing air-currents to pass betweenthe edge of the stripper and the periphery of the roller into thecasing.

6. In a cotton-gin, the combination with a grooved roller and a casingpartially inclosing same, of a stripper forming a closure for the casingat one side of the said roller, and arranged with its edge in closeproximity to the said roller, and means for setting air-currents inmotion between the edgeof the stripper and the periphery of the rollerinto the casing.

7. In a cotton-gin, the combination with a spirally-grooved roller and acasing partially inclosing same, of a stripper forming a closure for thecasing at one side of the saidroller,

roller'and a casing partially inclosing same, of a stripper formingaclosure for the casing at one side of the said roller, and arrangedwith its edge in close proximity to the said roller, and suctionapparatus connected with the said casing.

9. In a cotton-gin, the combination with a grooved roller and a casingpartially inclosing same, of a stripper forming a closure for the casingat one side of the said roller, and arranged with its edge in closeproximity to the said roller, and suction apparatus connected with thesaid casing.

10. In a cotton-gin, the combination with a spirally-grooved roller anda casing partially inclosing same, of a stripper forming a closure forthe casing at one side of the said roller, and arranged with its edge inclose proximity to the said roller, and suction apparatus connectcd withthe said casing.

11. In a cotton-gin, the combination with a casing and a roller arrangedpartially within and partially without the said casing, of suctionapparatusconnected to the said casing.

12. In a cotton-gin, the combination with a casing and a grooved rollerarranged partially within and partially Without the said casing. ofsuction apparatus connected to the said casing.

13. In a cotton-gin, the combination with a casing and aspirally-grooved roller arranged partially Within and partially withoutthe said casing, of suction apparatus connected to the said casing.

. 1 1. In a cotton-gin, the combination with a casing and a hopper, of aginning-roller arranged partially within the casing and partially withinthe hopper, a stripper at one side of the said roller between the saidhopper and the said casing, and means for causing air-currents to flowfrom the hopper past t e stripper to within the casing.

15. In a cotton-gin, the combination with a casing and a hopper, of aginning-roller arranged partiallywithin the casing and partially withinthe hopper, a stripper at one side of the said roller between the saidhopper and the said casing, and a suction apparatus connected with thesaid casing.

16. In a cotton-gin, the combination with a casing e, and aginning-roller (0 arranged with a portion thereof within the saidcasing, the said casing having a portion thereof, as It, in closeproximity to the periphery of the roller on one side thereof, andprovided with a stripper g, in proximity to the roller, on the oppositeside thereof, of a suction apparatus connected to the said casing,substantially as set forth.
